Hydraulic Articulated Cylinder for Shield Tunneling Machines

The hydraulic articulated cylinder of a shield boring machine is a hydraulic cylinder used for articulated connections, which usually has a larger range of motion so that the machinery can have more working flexibility. In the process of shield driving, the hinged cylinder plays the role of connecting and supporting various parts of the shield machine, and can adapt to different driving angles and directions. This kind of cylinder also needs to have good sealing performance to avoid dust and other substances entering the hydraulic cylinder and affecting its working effect. The stability and durability of hinged cylinders have an important impact on the overall performance and driving efficiency of shield machines.

Hydraulic Articulated Cylinder for Shield Tunneling Machines

A hydraulic articulated cylinder is a specialized hydraulic cylinder designed for shield tunneling machines, enabling articulation or movement of its body, unlike standard hydraulic cylinders with a fixed body. These cylinders serve numerous functions in shield tunneling machines, including:

  • Active articulation: Steering the cutter head and coordinating tool changes. The hydraulic cylinder articulates the cutter head, facilitating steering and tool changes without halting the machine.
  • Passive articulation: Assisting in dragging the tail of the shield forward. This feature helps propel the machine forward through the ground.

Hydraulic articulated cylinders for shield tunneling machines are constructed from high-strength materials, designed to
